ClassNotFoundException when trying to use quasiquotes and Paradise plugin

[Zoop]

Hi,

I'm trying to use the Paradise compiler plugin to use quasiquotes in my project.  I get the following error from Scala IDE:

These are my Eclipse details:

I'm using Scala IDE 4.0.0.v-2_11-2015

Your project is on 2.10, right? I think at this point there is no workaround (compiler plugins aren't supported in 2.10 mode... though it should not crash, that's a bug)
